This paper investigates the potential impacts of the degree of divergence in open macroeconomic policies in the context of the trilemma hypothesis. Using an index that measures the relative policy divergence among the three trilemma policy choices, namely monetary independence, exchange rate...

The well-known uncovered interest parity puzzle arises from the empirical regularity that, among developed country pairs, the high interest rate country tends to have high expected returns on its short term assets. At the same time, another strand of the literature has documented that high real...

We provide a theory of the determination of exchange rates based on capital flows in imperfect financial markets. Capital flows drive exchange rates by altering the balance sheets of financiers that bear the risks resulting from international imbalances in the demand for financial assets. Such...

Historical data for over hundred years and 14 countries is used to estimate the long-run effect of productivity on the real exchange rate. We find large variations in the productivity effect across four distinct monetary regimes in the sample period. Although the traditional Balassa-Samuelson...

Fluctuations in commodity prices are often associated with macroeconomic volatility. But not all nations are created equal in this regard. The macro response to commodity booms and busts depends both on the structural characteristics of the economy and on the policy framework that is in place....

This paper studies the effect of transport infrastructure on the real exchange rate (RER) and reaches two relatively strong conclusions. First, while the list of robust determinants of the RER is not long, transport infrastructure belongs to that list. Many other potential determinants proposed...

Fiat money contains the seeds of its own destruction. It has no intrinsic value and, yet, it can be exchanged for valuable consumption and production goods. As Hahn (1965) shows, this situation puts fiat money's market value or liquidity premium at the brink of collapse. In this paper I will...

This paper characterizes jointly optimal default and exchange-rate policy. The theoretical environment is a small open economy with downward nominal wage rigidity as in Schmitt-Grohé and Uribe (2013) and limited enforcement of international debt contracts as in Eaton and Gersovitz (1981). It is...

We investigate the link between real exchange rates and sectoral total factor productivity measures for countries in the Eurozone. Real exchange rate patterns closely accord with an amended Balassa-Samuelson interpretation, both in cross-section and time series. We construct a sticky price...

This paper addresses the issue of the optimal stock of international reserves in terms of a statistical model in which reserves affect both the probability of a Sudden Stop-as well as associated output costs-by reducing the balance-sheet effects of liability dollarization. Optimal reserves are...
